问题描述






之前:

我想要将缩排/未缩进区域的两个键绑定定义为4个空格。 h3>

  hello 
world
foo
bar
/ pre>


  • 目视选择 world foo

  • 键入





  hello 
world
foo
bar






我也想绑定到unindent区域。 br>
我不熟悉 emacs 请帮助。

解决方案

已经有键盘快捷键:



缩进:



Unindent



如果您发现输入时间过长,可以将以下内容添加到.emacs文件:

 (defun my-indent-region(N)
(互动p)
(if(use-region-p)
(progn(indent-rigidly(region-beginning)(region-end)(* N 4))
set $ n $)
(self-insert-command N))

(defun my-unindent-region(N)
(interactivep)
(if(use-region-p)
(progn(indent-rigidly(region-beginning)(region-end)(* N -4))
(setq deactivate-mark nil) )
(self-insert-command N))

(全局设置键>'我的缩进区域)
(全局设置键<'my-unindent-region)

使用这段代码, / em>()和小于()键将会将标记的区域缩进/取消标记4个空格。 p>

I want to define two key-bindings to indent/unindent region by 4 spaces.


Before:

hello
world
foo
bar

  • Visually select world and foo.
  • Type

After:

hello
    world
    foo
bar


I also want to bind to unindent region.
I'm not familiar with emacs, please help.

解决方案

There are already keyboard shortcuts for that:

Indent:

Unindent

If you find that too long to type, you could put the following in your .emacs file:

(defun my-indent-region (N)
  (interactive "p")
  (if (use-region-p)
      (progn (indent-rigidly (region-beginning) (region-end) (* N 4))
             (setq deactivate-mark nil))
    (self-insert-command N)))

(defun my-unindent-region (N)
  (interactive "p")
  (if (use-region-p)
      (progn (indent-rigidly (region-beginning) (region-end) (* N -4))
             (setq deactivate-mark nil))
    (self-insert-command N)))

(global-set-key ">" 'my-indent-region)
(global-set-key "<" 'my-unindent-region)

With this code the greater than () and less than () keys will indent/unindent a marked region by 4 spaces each.
